Good info. I found the GI ball to drop too much at 100 yards. A Hornady 185 gr JHP with a max load of Unique made a big difference. How about trying Elmer's SWC 45 bullet in the 45 ACP? It should feed in the Glock.
Real nice shooting! Do you alter your trigger manipulation when switching from revolver to semiautomatic? I used to, but have found that if I just keep my finger in the same spot on my trigger finger I have the best results.
I don’t think of the trigger press any differently but the follow through is different. I let my arms absorb the recoil when shooting revolvers but try to hold semi-autos down so they will cycle properly.
